+Read information about the operating system using the OS Information plugin.
+
+## Setup
+
+Install the OS Information plugin to get started.
+
+<Tabs>
+    <TabItem label="Automatic">
+
+    1. Use your project's package manager to add the dependency:
+
+    <CommandTabs npm="npm run tauri add os"
+    yarn="yarn run tauri add os"
+    pnpm="pnpm tauri add os"
+    cargo="cargo tauri add os" />
+
+    2. Modify `lib.rs` to initialize the plugin:
+
+    {/* TODO: Revise once https://github.com/tauri-apps/tauri/issues/7696 is in */}
+
+    ```rust
+    #[cfg_attr(mobile, tauri::mobile_entry_point)]
+    pub fn run() {
+        tauri::Builder::default()
+            // Initialize the plugin
+            .plugin(tauri_plugin_os::init())
+            .run(tauri::generate_context!())
+            .expect("error while running tauri application");
+    }
+    ```
+
+    </TabItem>
+    <TabItem label="Manual">
+
+    1. Run `cargo add tauri-plugin-os` to add the plugin to the project's dependencies in `Cargo.toml`.
+
+    2. Modify `lib.rs` to initialize the plugin:
+
+    ```rust
+    // lib.rs
+    #[cfg_attr(mobile, tauri::mobile_entry_point)]
+    pub fn run() {
+        tauri::Builder::default()
+            // Initialize the plugin
+            .plugin(tauri_plugin_os::init())
+            .run(tauri::generate_context!())
+            .expect("error while running tauri application");
+    }
+    ```
+
+    3. If you'd like to use in JavaScript then install the npm package as well:
+
+    <CommandTabs
+        npm="npm install @tauri-apps/plugin-os"
+        yarn="yarn add @tauri-apps/plugin-os"
+        pnpm="pnpm add @tauri-apps/plugin-os"
+    />
+
+    </TabItem>
+
+</Tabs>
+
+## Usage
+
+With this plugin you can query multiple information from current operational system. See all available functions in the [JavaScript API](/2/reference/js/os/) or [Rust API](https://docs.rs/tauri-plugin-os/) references.

+
+#### Example: OS Platform
+
+`platform` returns a string describing the specific operating system in use. The value is set at compile time. Possible values are `linux`, `macos`, `ios`, `freebsd`, `dragonfly`, `netbsd`, `openbsd`, `solaris`, `android`, `windows`.
+
+<Tabs>
+<TabItem label="JavaScript">
+
+```js
+import { platform } from '@tauri-apps/plugin-os';
+
+const platform = await platform();
+console.log(platform);
+// Prints "windows" to the console
+```
+
+</TabItem>
+<TabItem label="Rust">
+
+```rust
+let platform = tauri_plugin_os::platform();
+println!("Platform: {}", platform);
+// Prints "windows" to the terminal
+```
+
+</TabItem>
